Hello, a bit more data on the problem of "_id" column not existing, a post that I had made earlier. Inside of my query in a ContentProvider I attempt to read the database. The error points back to the "_id" no such column. I don't get it? I have tried upper case and lowercase "_id" name. the column is there as you can see in the Log output.
I am still working on it but?? thanks Jeff public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE " + MEDS_TABLE_NAME + " (" + Meds._ID + " INTEGER PRIMARY KEY autoincrement," + Meds.sMEDS_FK + " INTEGER ," + Meds.sSTATUS + " TEXT," + Meds.sSOURCE + " TEXT," + Meds.sPRODUCT + " TEXT," + Meds.sDIRECTIONS + " TEXT," + Meds.sFULLFILLHISTORY + " TEXT," + Meds.sCREATION_DATE + " TEXT," + Meds.sMODIFIED_DATE + " TEXT" + ");"); Log.w(TAG, "onCreate"); } <b>Insert is working:</b> long rowId = db.insert(MEDS_TABLE_NAME, Meds.MED, values); Log.e(TAG, "aft insert rowId = " + rowId); LOG --11-21 08:32:30.983: ERROR/MPhrProvider(195): aft insert rowId = 10 if (rowId > 0) { Uri medUri = ContentUris.withAppendedId (MPhrDef.Meds.CONTENT_URI, rowId); // append rowid at end of givin uri getContext().getContentResolver().notifyChange(medUri, null); return medUri; SQLiteDatabase db = mOpenHelper.getReadableDatabase(); Cursor c = qb.query(db, projection, selection, selectionArgs, null, null, null); Log.e(TAG, "OnCreate cursor.getColumnName0 = " + c.getColumnName(0)); Log.e(TAG, "OnCreate cursor.getColumnName1 = " + c.getColumnName(1)); 11-21 09:10:19.120: ERROR/MPhrProvider(195): OnCreate cursor.getColumnName0 = _ID 11-21 09:10:23.240: ERROR/MPhrProvider(195): OnCreate cursor.getColumnName1 = SOURCE detailMessage "Invalid column _ID" -------------- Here I changed the case of _ID to _id (lower) Cursor c = qb.query(db, projection, selection, selectionArgs, null, null, null); Log.e(TAG, "OnCreate cursor.getColumnName0 = " + c.getColumnName(0)); Log.e(TAG, "OnCreate cursor.getColumnName1 = " + c.getColumnName(1)); LOGCAT [0] "_id" [1] "SOURCE" String[] p = {"_id", "SOURCE", "PRODUCT"}; String st = qb.buildQuery(p, selection, selectionArgs, null, null, orderBy, null); Cursor cc =db.rawQuery(st, null); 11-21 09:28:57.376: ERROR/MPhrProvider(194): OnCreate cursor.getColumnName0 = _ID 11-21 09:29:12.129: ERROR/MPhrProvider(194): OnCreate cursor.getColumnName1 = SOURCE com.sun.jdi.InvocationException occurred invoking method.
